NVIDIA GeForce GTX 1080 (Desktop) vs NVIDIA GeForce GTX 1060 Max-Q vs NVIDIA GeForce GTX 1080 SLI (Laptop)

NVIDIA GeForce GTX 1080 (Desktop)

Die Nvidia GeForce GTX 1080 ist nach dem Topmodell Titan X die zweitschnellste Pascal-Grafikkarte für Desktop-PCs und wurde im Mai 2016 vorgestellt. Die GPU verfügt über die vollen 2.560 Shadereinheiten des zugrundeliegenden GP104-Chips sowie 8 GB GDDR5X-Speicher an einem 256-Bit-Interface (10 GHz, 320 GB/s).

Features

Der GP104-Chip wird in einem 16nm-FinFET-Prozess bei TSMC gefertigt und bietet eine Reihe neuer Features, unter anderem Support für DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) sowie verbessertes H.265 Video De- und Encoding (PlayReady 3.0). Eine genaue Auflistung der Verbesserungen und Features der neuen Pascal Desktop-GPUs finden Sie in unserem Pascal-Architektur-Artikel.

Performance

Die Performance der GeForce GTX 1080 liegt etwa 65 Prozent über dem Vorgänger GTX 980 sowie 30 Prozent oberhalb der GTX 980 TI und Titan X (Maxwell). Damit ordnet sich die GTX 1080 im absoluten High-End-Segment ein und kann die meisten Spiele des Jahres 2016 in hohen Einstellungen und 4K-Auflösung flüssig darstellen.

Leistungsaufnahme

Die Leistungsaufnahme der GeForce GTX 1080 wird vom Hersteller mit 180 Watt beziffert und liegt damit nur leicht über dem Vorgänger GTX 980 (165 Watt).

NVIDIA GeForce GTX 1060 Max-Q

The Nvidia GeForce GTX 1060 with the Max-Q design is a mobile high-end GPU from the Pascal series. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1060 for laptops based on the cooling capabilities. The base frequency (1063-1265 MHz) is also much lower than on the regular GTX 1060 (1506 MHz, at least -16%) and the Boost (1341-1480 MHz) is also much lower compared to 1708 MHz (at least -13%) for the regular GTX 1060. The memory clock, however, is identical.

The clock is not the only difference compared to the regular GTX 1060 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

Features

The GP106 chip is produced in 16nm FinFET at TSMC and offers a range of new features, like DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and improved H.265 video de- and encoding (PlayReady 3.0). A list of improvements and features can be found in our article on the Pascal architecture.

The power consumption of the Max-Q design is notably lower than the normal GTX 1060 for laptops and ranges between 60 and 70 Watt (TGP) according to Nvidia.

NVIDIA GeForce GTX 1080 SLI (Laptop)

The Nvidia GeForce GTX 1080 SLI for laptops is a combination of two GTX 1080 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1080 to up to 90% faster performance. Sometimes, the combination may also suffer from micro-stuttering. The technical details of the card are identical to a single GTX 1080 (see for more information) and the power consumption is doubled. Therefore, the 1080 SLI combination is only found in huge clunky laptops.
